Hot-pressed Fe2+:ZnSe transparent ceramics with different doping concentrations
Source abstract
Abstract
Abstract In this study, Fe2+:ZnSe transparent ceramics with different doping concentrations were prepared from annealed FeSe and ZnSe powders by hot pressing. The as-prepared ceramics consisted of a cubic ZnSe phase and compact microstructures. Doping concentrations of Fe2+ ions in the range 0.66–3.05 at.% were accurately realised, which could influence the absorption intensity of Fe2+:ZnSe transparent ceramics. An absorption peak was observed at ∼3 μm, and its intensity could be controlled by the concentration of Fe2+ ions. FexZn1-xSe (0.0066 ≤ x ≤ 0.0305) ceramics with Fe2+ ions concentrations in the range 0.66–3.05 at.% exhibited significant absorption cross sections from 0.6676 × 10−19 to 0.1075 × 10−18 cm2. The specimen doped with 1.55 at.% Fe2+ ions displayed the highest transmittance of 67% at a wavelength of 14 μm and a carbonate absorption peak at 9 μm. The proposed transparent ceramic technique appears promising for preparing Fe2+:ZnSe laser gain media because of its advantage of allowing control over Fe2+ concentration.
